Stove parts that require replacing most frequently are the burner, gaskets, leather pump cup and nozzle picks. You may get several years of part time service from the stove without using the spares if you use clean fuel and don't abuse it. Full time live-aboard cooks should have spares in stock.

(Update: Though my stove kits are no longer being produced, for those who want to make their own gimbal system, you may find a similar camp stove to the one pictured above on ebay or other online sources. They used to be available from St Pauls Merchantile, though I heard he had a factory fire in 2013 that at least temporarily closed the business. Some stoves have different burner thread size and pump diameter from mine, and the flame ring and preheat cup on other stoves are probably plated steel instead of solid brass. If you're concerned about them rusting, I have spares in stock that to retrofit those two parts.)
